15. fItted heater

The electrical fitted heaters of the RDU1STB series are the main heater for electrically heated hot water heaters. Under
normal circumstances, they do not require any maintenance or other service intervention. However, if the lime concentra-
tion of the water is very high, it may be necessary to remove the boiler scale at certain intervals.
The range of electrical fitted heaters of Austria Email AG is manufactured in conformity with the applicable rules and re-
gulations.
The fitted heater features a safety temperature limiter that switches off any further heating of the unit when the water
temperature reaches max. 110° C (EN 60335 -2-21; ÖVE-EW41, Pt 2 (500) / 1971). Therefore, when selecting the con-
nection components (con-nection pipes, safety valve combinations, etc.), it is necessary to ensure that the connection
components will withstand temperatures of 110° C so that any consequential damage in the event of a malfunction is
prevented.

16. saVIng energy

Selecting a low water temperature setting for the water in the storage tank saves a lot of energy. Consequently, it is ad-
visable to set the infinitely variable temperature controller to the lowest temperature setting required for your actual hot
water consumption. This reduces your electricity consumption and the lime deposits in the tank.

17. safety teMperature lIMItatIon

The built-in electrical heating is designed without a temperature regulator.
The mounted safety temperature regulator (STB) stops the power supply to the electrical heater at a temperature of 100
°C (±7 °C) in accordance with EN 60335-2-21.
GB
Due to the hysteresis (±7 °K) and potential radiation losses (cooling of the plumbing) the temperatures quoted are subject
to a tolerance of ± 10 °K.

17.1 Heating-up times

Table for the determination of the connected load (kW, fitted heater type) to heat the tank water from 10° C to 85° C
(reduction factor if tank water is to be heated from 10° C to 65° C: multiply value give in the table by 0.73). Flange tube
